The implication here is that your home directory can actually work across distros? How in the world do you do that? Surely you have to encounter errors sometimes when cached data or configs point to nonexistent paths, or other incompatibilities come up?
Typically ~ contains user specific config files for applications, which are (usually) programmed to be distro agnostic. If you're installing the same applications across distros, I don't see why this wouldn't work without too much effort. After all, most distros are differentiated by just two things:
- their package management tooling
- their filesystem layout (eg where do libraries etc go)
